Title: Improvements in and relating to connections for articulated railway and like carriages
IPC: B61F3/12
Filed: 1935-08-26
Abstract: 457,558. Railway &c. vehicle couplings. DEVLIN, S. R., 9,' Buller Street, Derby. Aug. 26, 1935, No. 23887. [Class 103 (v)] In an articulated railway &c. vehicle the adjacent ends of two carriages are supported upon a single-axle bogie, which is associated with means for permitting the necessary articulation whilst at the same time preventing relative lateral or vertical movement between the two carriage bodies. In the construction shown the adjacent ends 11, 12 of the carriage underframes are adapted to pivot on bearings 13, 14 on a pair of transverse bolsters 25, 26 which in turn are supported by springs 23, 24 on planks 21, 22 suspended from the bogie frame 18 by swinging links 20. A tooth or projection 48 with curved faces on the underframe 12 enters a recess 49 on the underframe 11 to prevent relative displacement other than the desired articulation. These interengaging elements of the two carriages may either be formed integrally with the underframes or be secured thereto by bolts or equivalent. They may also take the form of interengaging involute teeth, or of one or more links hinging about vertical pivots on the two carriages. In place of the swinging bolsters 25, 26, bolsters rigid with the frame 18 may be employed.

Title: Improvements in and relating to the production of refractory substances
IPC: C04B35/01
Filed: 1931-08-25
Abstract: A refractory material is produced by melting together the oxides of chromium, aluminium, iron, and magnesium so that at least 80 per cent of the product contains these oxides in proportions corresponding to the spinel formations MgOCr2O3, FeOCr2O3, MgOAl2O3, and FeOAl2O3 and contains at least 4 molecules of MgO to 1 molecule FeO and not more than 8,5 molecules Al2O3 to 1 molecule Cr2O3, the remainder which may be considered as a cement containing not more than 11 per cent of silicic acid.  Where, however, an excess of chromium oxide over the amount required for spinel formation is present, the quantity of non-spinel formers (including the excess chromium oxide) may rise to 25 per cent so that the material contains 75 per cent of spinel formation.  The main constituent of the material produced is represented by:- <FORM:0382014/V/1> where z < 1, y < 2 and x < 2. Several mixtures conforming with the invention are given. Specifications 302,087, 324,312, [both in Class 22, Cements &c.], and 343,896 are referred to.

Abstract: 703,726. Supplying liquid fuel to burners. JET-HEET, Inc. Oct. 16, 1951, No. 24093/51. Class 75 (1) A liquid fuel burner system comprises a spray nozzle 45, Fig. 3, of the return flow type, a pump 44 for supplying fuel to a cylinder 11 to move a piston 26, Fig. 1, therein against the action of a spring 35 to expose and to allow fuel to flow through a port 36 intermediate the ends of the cylinder 11 to the nozzle supply conduit 39, and on the stopping of the pump 44 the piston 26 is returned by the spring 35 to suck fuel from the conduit 39 and also from the fuel return conduit 51 connected between the nozzle 45 and a port 18 opening into the cylinder 11 beyond the piston at the maximum spring compressing position of the latter. The piston 26 has external grooves 28, 29 formed between flanges 30, 31, 32, a sealing ring 33 being disposed in the groove 28, and the flange 32 having holes 38 for the passage of fuel. The cylinder 11 is formed in a body 10 having an extension 16 receiving the spring 35 and formed with threaded openings 19, 20. 21 communicating with the port 18. The opening 20 receives the conduit 51, the opening 19 being connected to a conduit 52 leading through a pressure. regulator 50 to the fuel supply tank 41, and the opening 21 being either plugged or connected to a pressure gauge. The ports 18, 36 are preferably of equal size so that the piston 26 when moved by the spring 35 draws fuel from the conduits 39, 51 at about equal rates. A pressure regulating valve 56 controls the fuel pressure m the fuel supply conduit 25 and may have connected in parallel therewith a solenoid operated relief valve, responsive to a thermostat which by-passes the fuel supply to the cylinder 11 and thus to the nozzle 45 when heat is no longer required. The cylinder 11 is preferably disposed below the level of the nozzle 45 so that no fuel will flow by gravity to the latter when the piston 26 operates to withdraw fuel from the conduits 39,'51. Specification 696,335 is referred to.

Title: Improved process of treating fabrics having a cellulose acetate pile
IPC: D06P1/00
Filed: 1930-08-12
Abstract: Fabrics, treating with liquids; printing; cellulose acetate, dyeing.--Fabrics having a cellulose acetate pile are printed or padded with a solution of regenerated cellulose in caustic alkali to obtain a local or all-over deposition of cellulose.  The fabric, after treatment with the solution, may be dried and the alkali neutralized.  The cellulose solution may be prepared by dissolving the regenerated cellulose in an 8-12 per cent aqueous solution of caustic soda or potash and a further addition of regenerated cellulose may be made to bring the solution to a consistency suitable for printing without the addition of other thickeners.  In an example a cold gelatinous solution of viscose artificial silk in a cold 10 per cent solution of caustic soda is applied by padding or printing to an artificial silk velvet, the fabric is dried, and the alkali is neutralized with acetic acid; on treatment with a cotton dye the cotton backing and the deposited cellulose are coloured leaving any untreated cellulose acetate pile white and lustrous.  By applying the regenerated cellulose solution at a higher temperature the lustre of the cellulose acetate may be dulled.  Pattern effects are also obtainable after an all-over deposition of the cellulose by dyeing and printing the dyed fabric with a discharge paste.  Specificatio 297,607, [Class 42 (i), Fabrics, Finishing &c.], is referred to.

Abstract: 640,230. Controlling change-speed gearing. ROLLS-ROYCE, Ltd. Aug. 19, 1946, No. 24685. [Class 80(ii)] [Also in Group XXXVII] In a change-speed gear having a ratio change effected by operation of the accelerator pedal or like member controlling the power input, a dashpot device is associated with the pedal in such a manner that the ratio change is effected only by movement of the pedal above a predetermined rate. As shown, the invention is applied to the gearing described in Specification 640,228 in which a dog clutch member 29, Fig: 2, is slidden out of engagement with a co-acting member on a gear 11 under the action of a solenoid 46 to change down from direct drive. The accelerator pedal 50, Fig. 3, is connected' to the piston 53 of a dashpot; the cylinder 51 of which has a bleed hole 52 to allow the passage of air, other fluid or, according to the Provisional Specincation, a liquid, at such a rate that normal working of the pedal does not affect the cylinder 51. Upon unusually rapid depression of the, pedal, 5.0 the dashpot acts as a solid link and the cylinder 51 moves against a spring 56 to close a switch 49 in the solenoid circuit and causes the member 29 to disengage. Re-engagement of the member 29 under the action of a spring 44 upon subsequent opening of the switch 49 by the spring 56 is prevented by a device of the kind set out in Specification 640,227 until the speeds of the members 29, 11 are synchronized. The pedal 50 also closes the switch 49 mechanically when the piston 53 reaches the bottom of the cylinder which may occur at the full, throttle position. Actuation of the switch 49 may be arranged momentarily to disable the ignition of a driving internal combustion engine so as to. unload the torque on the member 29 during disengagement thereof. The dashpot may be replaced by an equivalent device operating electrically:
